After giving the Chevy Silverado and GMC Sierra pickups a thorough rework for 2015, GM has pulled the wraps off its latest and greatest full-sized SUVs. As with their pickup siblings, the Chevy Tahoe and Suburban, and the GMC Yukon and Yukon XL, have undergone a complete redesign inside and out, bringing improved ergonomics, better refinement and an upmarket push.

Part of the latter strategy includes more emphasis on the Yukon Denali moniker. The overall design may look similar to lesser Yukon, Suburban and Tahoe models, but more upscale touches have been worked into the SUV, including different wheel designs, real wood and aluminum accents inside and more supple leather. To keep up with the times, the duo come standard with keyless entry and push-button start, a power rear tailgate with programmable height settings and an eight-inch touchscreen entertainment system as standard on the Yukon and optional on the Suburban and Tahoe.

Powering GM’s crop of full-sized SUVs is the EcoTec3 family of engines. The Suburban, Tahoe and Yukon all come standard with a 5.3-litre V8 good for 355 horsepower and 383 lb.-ft. of torque. Opt for the Yukon Denali and you get a 6.2-litre V8, pumping out 420 horsepower and 460 lb-ft of torque. GM’s one big happy family of full-size SUVs will hit dealers sometime in the new year.
